KEYLESS rAnLocK.

I To all whom it may concern:

Be it known that I, JOHN KARIN, a subject of the Emperor of Austria, residing at Koppel, in the county of Beaver and State of Pennsylvania, have invented certain new and useful Improvements in Keyless Padlocks, of which the following is a, specification.

This invention relates to an improved padlock and the principal object of the invention is to provide a padlock having a latching arm which is mounted in the body portion or housing of the lock and engages the hooked end of the shackle to releasably hold the shackle in the closed position, improved means being provided for releasably holding this latching arm in an operative position.

Another object of the invention is to so construct the securing disks for the latching arm that they may securely hold the latching arm in the operative position by engagement with lugs ,or fingers extending from the arm which lugs or fingers will pass through cutouts in the disks when moved to the proper position for permitting the latching arm to move to an inoperative position and release the shackle.

Another object of the invention is to provide a lock which will be very compact and which will comprise a very few number of parts.

Another object of the invention is to so construct this look that no spring is necesrs sary in order to have the lock operate properly.

This invention is illustrated in the accompanying drawings, wherein Figure 1 is a view showing the lock in side elevation with the shackle indicated in the released position by dotted lines.

Fig. 2 is a view showing the lock with one of the side walls removed.

Fig. 3 is a sectional view through the lock taken on the line 33 of Fig. 2.

F lg. 4 is a perspective view of the latching arm.

Fig. 5 is a perspective view of one of the disks serving to releasably hold the latching arm in an operative position.

The body portion or housing of this padlock includes a frame 11 and side walls i; 12 which are connected with the frame by means of rivets or other fasteners 13. It is of course understood that if desired, one of these walls could be formed integral with Specification of Letters Patent.

frame 10 "by means of the pin 15 and is provided with a hook 16 at its free end.

which will pass through an inlet opening 17 V for engagement with the hooked end 18 of the latching arm 19. This latching arm 19 is pivotally mounted .in the housing by means of the hinge bracket 20 and is provided with side arms 21 serving to prevent outward longitudinal movement of the latching arm when in an operative position. A pin 22 extends through the housing and through an. opening 23 in the latching arm and may be connected with the latching arm so that this pin can serve as means for swinging the latching arm to an inoperative position. Disks 24 and 25 are mounted upon the stems or pins 26 and 27 and are provided with cutouts 28 and 29 so that when the stems or pins 26 and 27 are turned to the proper position bymeansof the knobs 30 and 31, the fingers 32 and 33 may pass through the cutouts 28 and 29. These disks overlap the fingers when in the position shown in Fig. 2 and prevent the latching.

arm from moving to a releasing position and unless the operator knows the proper point at which to turn the pointers 34 and 35 upon the dials 36 and 37 the padlock cannot be opened. It is of course, understood that the shape of the fingers may be changed and of course the shape of the cutouts in the disks to correspond with the fingers and further that the arrangement of fingers may be changed when making the" ried by the body portion and having its free end engaged by the latching arm, fingers extending fromthe latching arm, and

locking disks movably mounted in the body portion and extending in overlapping relation to said fingers when in an operative position. and provided with cutouts through which the fingers may pass to permit the latching arm to move to an inoperative position when the locking disks are in an inoperative position.

2. A look comprising a hollow body portion, pins rotatably carried by said body portion and extending through the same, disks carried by said pins in said body portion, a latching arm pivotally mounted in said body portion for transverse movement therein,. and a shackle pivotally connected with said body portion and having its free end portion extending into said body portion and engaged by said latching arm,'said disks when moved to an operative position .5 extending in overlapping relation to the movement therein and engaging the free end of said shackle said latching arm being provided with side arms for engaging the Wall of the body portion to prevent longitudinal movement of the latching arm in one direction, fingers extending from said latching arm, pins extending through said body portion, and disks carried by said pins and provided with cutouts through which said fingers may pass to permit said latching arm to move to an inoperative position, said disks when in an operative position extending in overlapping relation to the fingers to prevent pivotal movement of the latching arm.

In testimony whereof I aflix my signature in presence of two witnesses.
